Application filed anuary 20, 1922.

To all wibo/HL t may concern.' I

lle it lrnown that l, Env/ann ti. litlrnsrvr, a citizen of the Unitedtates7 residing at Taylor in the count ot Laelrawanna` and State yn 7 *nu v l I or lennsylvania', have invented certain new and usefulimprovements in Demountable Rims for Vehicle W heels, of which the 'ichlowing is a specilication.

My said invention relates to demountable rim for vehicle wheels andfinds its principal application in connection with wheels carrying`pneumatic tires. The object of the invention is to provide a rim ot thishind which will permit the tire to be readily removed and replaced.

Referring to the accompanying drawings wnich are made a part hereof andon which similar reference characters indicate similar parts,

Figure 1 is a perspective ot the device,

Figure 2 is a side elevation oit my device,

Figure is a plan of the same, and

Figure a section on line l-Jl o'f l `ig ure 2.

In the drawings 1G indicates the main web of my demountable rim having'flanges 11 and 127 the lirst ot which extends entirely around the web.A swngable rim-section has a radial flange 13 supplementing Aflange 12,this section being pivoted at 15 on thev body. The pivoted section hasalso a pair of plates 1G and 17 with wavy edges corre spending to a wavyedge at 18 on the body and supplementary to the main web. The plates 1band 17 are thinner than the main web and overlie estensione 19 thereon.This structure adds to the strength ol the device inasmuch as the part16 falling between said llanges 153 extends the iull width ot the tire.The tire slips easily into place and there is little danger ot pinchingit, in addition to which the parts are readily brought intoI assembledposition a'lfter the tire is mounted on the rim.

As one means 'for holding the parts in closed position l have shown alatch 20 pivotally mounted on the member 13, this latch having a boltportion 21 to pass into an openingin a lug 22 on the main web. rlhe bolt21 has a lug` 23 near its end (Figure e) to engage under the lug- 22 andhold the parts in locked relation. A lin 2li on an inward extension ofthe pivoted section 15 coacts with a notch in the bolt at 25 and helpsto hold tue bolt in locking relation. n. linger piece 26 is provided onthe latch :t'or

convenience in operating they same and this linger piece has arearwardly extending lug 'i to engage under the forward edge of the 22at 28, this engagement being` such that ug 2T can be forced past lug 22in either direction, but will not slip past under the action` olfgravityor due to any jarring action. lWhen` the tire is in place it entendsover thelatch andk prevents retraction thereof.

l have shown at 29 conventional means for preventing rotation of the rimabout the fel y of the wheel, the rim being` held on the telly by theusual wedges. Any other means may, however, be substituted torperforming these functions.

it will be evident to those skilled in the art that my device may bemodified in va` rions ways as by the use of a different form ol? latchor by different arrangement of parts. The true scope of the invention isset `'forth in the appended claims.

Having thus fully described my said inventiom what l claim as new anddesire to secure by Letters Patent, is: y

1. A demountable rim for vehicle wheels comprising a channeled memberhaving radially extending flanges and a web connectingl them, acomplemental member carrying a portion of one side flange and parts ofsaid web lugon said body member projecting through said complementalmemben and means for engaging the lug to hold the parts in operativeposition, substantially as set forth.

2. ln a demountable rim for vehicle wheels. a web, an annular flange atone side thereoit. a semi-circular flange at the other side. acomplementa-l member comprising a semi-circular ilangc and web portionshaving` wavy margins registering with corresponding portions ot the mainweb, said main web having thin extensions underlying` the flanges otsaid complemental member. substantially `as set forth.

3. A demountable lrim for vehicle wheels comprising a body having anannular :lange at one side and a substantially semi-annular flange atthe other7 a complementa-l member hinged thereon and carrying webportions with wavy outlines to register with corresponding formations onthe main web, a lug extending l'rom the main web through said flange onthe complemental member and means to engage said lug and hold the partsin operative relation, substantially as set forth.

4. A demountable rim for vehicle Wheels comprising a main Web, anannular flange at one eide thereof, a segmental flange at the oppositeside, hinges at the ends of said segmental flange and a membercomplemental to the web and the segmental flange carried by said hinges,a pivoted latch oarried by said member and a lug on the main Webextending through said member for engagement with the latch,substantially as Set forth.

5. In a demountable rim for vehicle Wheels, a main web having opposedannular flanges, a section oi one flange being hinged to swing away fromthe Web, and means to hold the pivoted section in operative positioncomprising a perforated lug on the main web extending through an openingin said section, a latch having a bolt extending through the perforationin the lug and a 20 hook to engage under the lug, said bolt having alsoa notch engaging a fin on the pivoted section,'a linger piece foroperating the latch and a lug extending rearwardly from the finger piece'for engaging underneath 25 Columbia, this 18th day of January, A.
